-  # "[node, mainnet]") rather than added in the dashboard Display name. This is
-  # deliberate: a Display name template like "... [${__field.labels.iac_group}]"
-  # would render an empty "[]" when the label is absent, and Grafana's
-  # renameByRegex transform runs on the pre-interpolation template so it cannot
-  # strip that "[]". Baking the brackets into the value means an absent group is
-  # simply an absent label -> the Display name renders nothing for it.

-  #   - resource_group: "[node]" or "[node, network]" when a network is present.
-  # Guards check != nil and != "" because OTTL Concat renders "<nil>" for an
-  # absent attribute, and the perf-iac collector stamps these with an empty-string
